Issues related to sustainability and development of renewable and less polluting processes are increasingly in evidence, due to the various environmental crises and a greater concern with the scarcity of non-renewable ...

The production process of 2nd generation ethanol (2G), using sugarcane bagasse, is a promising way to increase ethanol production without increasing the cultivation area. However, the process has been studied to become ...

Biosurfactants are amphipathic molecules produced by enzymatic or microbiological routes. Biosynthesis can occur by esterifying sugars with fatty acids, with lipase as the main enzyme that catalyzes the reaction. However, ...

R&D of (bio)chemical processes should include economic analysis and environmental assessment since the early stages of research, to improve the chance of successful industrial implementation. Process Systems Engineering ...

Extractive fed-batch ethanol fermentation using carbon dioxide (CO2) as striping gas has several advantages compared to the conventional fermentation, such as: reducing the effect of ethanol inhibition, allowing to use ...

Lignocellulosic biomass has been used as a sustainable alternative to organic derivatives of fossil origin for the production of intermediates and chemicals with higher added value. In this context, γ-valerolactone (GVL), ...

Potassium (K) plays an important role in several biochemical and physiological processes in plants, but the low concentrations of soluble K in the soil make it necessary to use chemical fertilizers in order to supply the ...

This study aimed to evaluate the air filtration performance of the fiber layer, produced by centrifugal spinning equipment, adhered to the surface of a commercial filter media applied to the internal ventilation system. ...

It is growing the number of studies related to alternative technologies allowing both, environmental remediation and clean energy production. In this sense, photocatalysis is a promising process, since it is sustainable ...

Brazil is the third largest beer producer in the world, with an estimated production of 14.1 billion liters of the product for the year 2018, generating several co-products throughout the process, being brewer’s spent grain ...

The industrial activities are the main cause of the particulate material emission, which results in the elevation of air pollution indices and respiratory diseases. One of the most common types of equipment to reduce emitted ...

Industrial processes are increasingly requiring environmentally sustainable technologies and the use of enzymes is relevant due to the selectivity and specificity of these biocatalysts. However, the application of soluble ...

Spouted beds feature the intense mixture of solids, which favors the mechanisms of heat and mass transfer. The understanding of these phenomena is associated with the difficult to obtain details of fluid dynamics by the ...

Because of its chemical versatility, ionic exchange and regeneration capacity, Layered Double Hydroxides (LDHs), have recently been recognized as a promising material due to their many application areas. Drying is an ...

Pneumococcus surface protein A (PspA) is a lactoferrin-binding protein that can be found on the surface of Streptococcus pneumoniae. The use of this protein as a carrier in the formulation of conjugate vaccines contributes ...

Two-dimensional (2D) cell culture has been the common platform for evaluating anticancer drugs. However, three-dimensional (3D) cell cultures, such as multicellular tumor spheroids (MCTS), best resemble tumor in vivo ...

Enzymes are biological catalysts that present diverse applications, representing interesting perspectives for use in several branches of the industry: agribusiness, biofuels, and pharmacist. However, the recovery of broth ...

The production of ethanol from xylose with the yeast Saccharomyces cerevisiae was initiated in the group with the SIF process (simultaneous isomerization and fermentation). This process allows total conversion of xylose, ...

Streptococcus pneumoniae diseases represent a widespread public health. Pneumococcal surface protein A (PspA), which is recognized as one of the main virulence factors of this bacterium, has gained relevance in coverage ...
